Title
Synthesis and Applications of Nanocrystalline Zeolites
Abstract: Zeolites are microporous crystalline materials with well-defined structures. Recently much emphasis has been accorded to the synthesis characterization and application of nanocrystalline zeolites driven by a wide choice of applications and the multitude of challenges they present to materials scientists. They are promising materials for the preparation of a variety of new and existing applications as in catalysts ion exchangers sensors optical devices etc.. The particle size of zeolites used for these applications is an important parameter. The synthesis and characterization of different zeolite structure in nanosized form are summarized. Special attention is given to zeolites synthesized as stable fully-dispersible sol. The use of fully-dispersible nanozeolites for the fabrication of hierarchical porous structures and transparent zeolite film are described. The application of nanozeolites and hierarchical porous nanozeolite structures for fine chemical synthesis are studied. Finally some future scope in this area is envisaged.Bio: Rosilda Selvin is an Associate Professor at King Abdulaziz University Jeddah Saudi Arabia with research interests in the design synthesis and study of nanomaterials including their application in catalysis. She gained her B.Sc. degree from Holy Cross College Nagercoil and her master’s degree in Industrial Chemistry from Alagappa University Karaikudi. She received her M.Phil in 1994 and Ph.D. in 2000 from Anna University Chennai working on Catalysis with Professor K.Rengaraj. From 2003 to 2005 she was a postdoctoral scholar in the laboratory of A.S.T. Chiang at the National Central University Taiwan where she developed a rapid synthesis procedure for nonagglomerated nanozeolites. She was invited to join as a faculty member at the Department of Chemical and Materials Engineering Lunghwa University of Science and Technology Taiwan where she set up a catalysis laboratory.
